Abstract: Delay Tolerant Network (DTN) is a challenge network that can tolerate long delays during connections. It is different from traditional networks because traditional networks cannot meet the needs of disrupted and challenged networks. In this article, we will discuss the delay-tolerant network bundling protocol, which is located between the application layer and the transport layer. It is used as a communication system to meet the needs of the Internet. Delay Tolerant Network (DTN) has a coordinated, long-term and profitable surplus. Therefore, most systems use the “Transfer by Key” policy for data transfer, but the main problem with this strategy is to choose the best queue and the best commit time. Therefore, in order to solve these problems, social systems are used to delay the network. After a detailed discussion of social relationships, three routing strategies were proposed based on location, conference-based routing, and community-based approaches. We have chosen a routing strategy for three of these protocols to compare socially sensitive, ie popular routing protocols, routing protocols and spray waiting for prophets and routing protocols. These protocols are compared using a simulator based on a discount rate, average latency, overload rate, and hop count used. After comparison, we conclude that the spray and hold routing protocol is based on the best choice of transfer rate, overload rate and hop count.
